The common auxiliaries of ethnic grouping and nationality denote the nationality or ethnic aspects of a subject represented by a main UDC number. They are derived mainly from the common auxiliaries of language =... (Table 1c) and so may also usefully distinguish linguistic-cultural groups, e.g. (=111) English speaking peoples (as opposed to the English)

Application Note

Political nationality (citizenship of nation-states) may be denoted, mainly by (=1:4/9) People living in countries of the modern world, which derive from the common auxiliaries of place (4/9) (Table 1e), but it may be found that for some subjects the place auxiliaries themselves will often serve as well. For special anthropogeography as a main subject see 572.9. CITATION ORDER. In citation order, a common auxiliary of ethnic grouping or nationality normally follows a main UDC number; it may, however, be cited medially or even first in a compound number if there is a need to group together documents or references on particular ethnic groups or nationalities
